  • Title: Regional variation in tooth size and pathology in fossil hominids.
    Author: Smith P.
    Journal: Am J Phys Anthropol; 1977 Nov; 47(3):459-66. PubMed ID: 412426.
    Abstract:
    Tooth size and dental pathology in fossil hominids were studied to test for regional differences in these parameters. The results showed little regional variation in tooth size for the Middle and Upper Pleistocene sites compared (except for Krapina) but considerable differences in the severity of attrition and dental pathology. These differences were considered indicative of regional differences in the functional load borne by the teeth, and in view of the similar technological status of the groups studied, were attributed to environmental differences in the diet. Since, in all regions, reduction in tooth size appeared to continue at the same rate for the periods investigated, no association can be established between presumed selective pressures related to differences in functional demands made on the dentition, and tooth reduction.
